OIL-HEATER.

Application filed April 12, 1916.

T 0 all whom it may concern:

Be it known that I, PHILIPP E. SOHEN- KENBERGER, a citizen of the United States, residing at Temvik, in the county of Emmons and State of North Dakota, have invented certain new and useful Improvements in Oil-Heaters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to oilers or lubricators for explosive engines, and has for its primary object to provide means for heating the oiler to insure a constant and uniform flow of the lubricant to the working parts of the engine.

Another object is the provision of a device of this character which will utilize the heat ed products of combustion from the engine in heating the oil.

With these and other objects in view, the invention consists in the novel construction, combination and arrangement of parts as will be hereinafter specifically described, claimed and illustrated in the accompanying drawing, in which:

Figure 1 represents a side elevation of the well known type 'of stationary explosive engine, illustrating the invention applied to use thereon, and Fig. 2 represents a fragmentary perspective view of the engine, illustrating part of the oil heater.

Referring to the drawing in detail, wherein similar reference numerals designate corresponding parts throughout the several views, the numeral 5 indicates a well known type of explosive engine having the usual exhaust pipe 6 and lubricating oil tank or container 7, which is connected with several of the working parts of the engine by oil pipes. The improved heater includes a flexible tube 8, which is connected at one end by a coupling 9 with the exhaust pipe 6 and the opposite end thereof is extended over and supported upon the cylinder of the engine 5 and is secured in position by a clamp- Specification of Letters Patent.

ing strap 10. The end of the heater pipe 8 opposite the exhaust pipe 6 is connected with a nozzle 11, the discharge end of which is so disposed as to direct the heated exhaust products of combustion passing through the tube 8 against the oil reservoir or container 7.

During operation of the engine a portion of the exhaust products of combustion are conducted from the tube 8 to the nozzle 11, which latter directs the heated gases against the oil reservoir 7, thereby effectively heating the oil and insuring a constant and uniform flow of the lubricant to the working.

parts of the engine.

Vvhat I claim is:

1. The combination with an explosive engine including a lubricant reservoir and an exhaust pipe, of means for conducting the exhaust products of combustion in proxiinity to said lubricant reservoir.

2. The combination with an explosive engine including an oil reservoir and an exhaust pipe, of a flexible tube connected with said exhaust pipe for directing the exhaust products of combustion from the en gine cylinder against said reservoir.

3. The combination with an explosive engine including an oil reservoir and an exhaust pipe, of a heater pipe communicating with said exhaust pipe and terminating in proximity to said reservoir for directing the products of combustion against said reservoir.

4:. The combination with an explosive engine including an oil reservoir and an ex haust pipe, of a heater pipe communicating with said exhaust pipe, and a nozzle connected with said heater pipe and arranged to direct the products of combustion against said reservoir.

In testimony whereof I atfix my signature in presence of two witnesses.
